Application Temperature Range R-134a performance suffers at lower evaporator temperatures. In general it is not applied at temperatures below -10F, and it is not necessarily the most economical overall choice in some other applications. Traditional R-12 type applications have adopted several products as alternatives, including R-134a, R-22, R-404A/R-507, and numerousretrofit blends.

Lubrication R-134a requires polyol ester (POE) lubricants, primarily for their ability to mix with HFC refrigerants. Traditional mineral oils and alkylbenzene do not mix with HFCs and will cause compressor failures. In addition, automotive air conditioning systems may also use polyalkaline glycol (PAG) lubricants (not typically seen in stationary equipment). Both POEs and PAGs will absorb moisture, and hold onto it, to a much greater extent than traditional lubricants. The moisture will promote reactions in the lubricant as well as the usual problems associated with water (corrosion, acid formation, etc.). The best way to dry a wet HFC system is to use a filter drier - run the system and change the drier - instead of relying on evacuation to clear the water.

Retrofitting Considerations Equipment built for R-12 will be sized a bit too small compared to equipment built for R-134a. In order to do the same job an R-134a system will need a larger compressor and larger heat exchangers. As a result a system which is retrofit from R-12 to R-134a will have lower capacity (run longer) and will probably develop higher head pressures (not enough condenser area). The lubricant will also need to be flushed and replaced with POE (residual mineral oil content less than 5%).

SEA FOAM liquifies gum and varnish deposits or internal engine components, removing carbon deposits, freeing sticky valve lifters and rings curing rough idle, pinging and hesitation problems. By using SEA FOAM to eliminate varnish and carbon buildup, mechanics can more accurately diagnose mechanical problems that may exist. That is why Sea Foam has been so popular with professional mechanics for over 65 years.

As a fuel system additive, Sea Foam will clean fuel injectors, clean carbon, gum and varnish deposits, add lubricity to fuel, stabilize fuel for 2 years and control moisture.

How to use Sea Foam in Tune-Up of Small 4 Cycle Carbureted Engine Lawn Mowers, Tillers, Edgers, Snowblowers, etc.

1. Start engine. If engine will not start, check spark and compression. If engine has spark and compression, pour a small amount up to 1/2 ounce into the carburetor throat. SEA FOAM will act as starting fulid and will start the engine unless there is a mechanical or electrical problem. With engine warm, keep on high idle and slowly pour one ounce through carburetor throat. Make sure exhaust is well ventilated when using in the carburetor as fumes will be extreme for a short time.

2. Pour 1/2 ounce to one ounce into small fuel tank and oil crackcase.

3. Immediate Results: Same as for large 4 cycle Autos, Trucks, Tractors, etc.

NOTE: One pint treats 8-25 gallons of gas (average one ounce per gallon) or 6-12 gallons of gas oil mix (average 2 ounces per gallon.) Does not replace oil. Use frequently.
